Chinese artist Kong Ning wears a costume symbolizing a butterfly, which is decorated with 365 masks on its wings to represent the number of days in a year, while holding a large kite in the shape of a mask during her performance art at the Badaling section of the Great Wall on the outskirts of Beijing January 1, 2015. Kong, whose works include themes related to China's air pollution problem, named her new performance art "Hua Die" (transforming into a butterfly) and performed it on the first day of the new year as she hopes that China has clean air for this year.
